Motherboard is way overkill and there are $20-$40 cheaper boards that do everything the same.
Can get 16gb RAM for $14 less.
PSU is WAY overkill and a unit can be had with the same quality for $70 less.
OK... I don't think there are lots of mobos at 120$ with a 5 year warranty, thermal control stuff, an independant IC for fans and otehr stuff. If there is, I've been living under a rock for a fea years
For editing, RAM with higher speed is primordial. 1600 MHz will see a drop in performance compared to 1866, and honestly, is it worth the 16$ less? I don't think so.
I do NOT think you can get a 860 watt PLATINUM PSU for 100$, but I do concede the Platinum rating is uncessary...
